Description of the Invention: [Technical Field] The present invention relates to a method for wireless communication and its phase-setting, in particular, a method for failing a link in a scale communication system, which utilizes at least one The timer, the method of utilizing at least the number and its associated equipment use at least - a timer, at least - a parameter and at least a _ variable number ^ = number, or a double-wood to handle the wireless link failure. [Prior Art] In the wireless communication system, the destruction of the signal by the wireless transmission environment, the situation of the unfavorable secret broadcast or the fault of the video transmission may cause the wireless link between the UE and the wireless network to fail (RadioLinkMurc, rlF). ). During the application service of the UE, if the wireless link fails, the user may immediately notice the delay of the service (Radio Β_·) used to provide the service. Therefore, many mechanisms fail on the wire side, require specific parameters and timers to trigger normal procedures, or wire the decision towel. For example, a Cell Update Procedure can handle wireless link failures and is not used to detect wireless link failures. Therefore, rebuilding a failed wireless link through these mechanisms can prevent users from being aware of service anomalies, or at least let the failed wireless link recover as early as possible. The client receives a timer (Timer) and a parameter (Parameter) from a System Information Block (SIB), such as T313, T314/Ding 315, N302, N315, N313, T302, or Ding 307, and utilizes partial timing. And parameters with 200818787 - combined counters (such as v3 〇 2) to handle some specific conditions. For example, when reconstructing a failed link, timers T314 and T315 are used as a rebuild timer that determines the timing of the secret-id mode (IDLEmode) after the cell update and reconfiguration decisions are made. Among them, the timers 314 and 315 are used in the field of line switching and packet switching services, respectively. For the base station (7) Qde_Bs), the timers T314 and D 315 are set by the wireless network controller and are usually larger than the set value of the one used. In contrast, in the long-term evolution system (L〇ngτ_Evolution, LTE) proposed by the 3rd Generation Mobile Communication Alliance, its service area only adopts packet switching technology, and will lead to more services and finer. Therefore, for the related mechanisms mentioned above, its preferred use in the long term evolution system has yet to be decided. In L, we use the Unisex M〇biie Telecommunications program. In the Long Term Evolution system, the 'UMTS' towel, the front face (F_xlHand·) wire restores the wireless link or the failed reset procedure. . When the normal handover fails and the user returns to the source base station, the client can initiate cell update to the target base station.

Although the long-term evolution is done - a service area, it does not mean - A service area only needs a dozen. In the universal mobile communication system, the timers in the two service areas can operate independently. In addition, 'no (four) sexual services, such as (4) (Realise) 'scale (four) services, will also Affects the timing (4) setting value. In the long-term development, the service and the new introduction will meet the requirements of various service products, and the sensitivity of the tree time for the failure of the wireless link, such as the out-of-synchronization state. In addition to considering the tolerance of the client (such as dual receiver or multiple connections), if multiple services or applications are simultaneously performed, the client will have at least one of the same frequency & Wireless link, Langshi monitors multiple frequency bands. ^ This 'has-the situation may occur in the terminal, that is, in a certain frequency layer (4) When the link fails, the other frequency layers maintain a good wireless link. The situation is that when the service provider entity turns, other services are still available for service. Therefore, even if the shacks have different services, they need separate timers. The use of a timer will be limited to 200818787. The receiving capability of the client's and affects services with different requirements (such as different service quality requirements). In the general mobile communication system, the timer is set by the wireless network control. However, the Long Term Evolution system has removed the wireless network controller and is used to set the network real-world level of the meter. It is also known that the System Architecture Evolution Bearer Service (10 SAE Bearer) Service) will be determined by the access gateway level (AGW). In addition, the functional entities at the gateway level also master the network configuration settings and the load status of the signaling and user level. Thus, the functional entity of the base station Will be able to respond faster to the transmission status. Furthermore, in the general mobile communication system, the timer T313 and the parameter N313 are used to detect The line link fails. The parameter N313 is the maximum value of consecutive de-synchronization indications (〇ut〇f 10 Sync Indications), wherein the out-of-synchronization indication comes from the first layer (the physical layer); the timer T313 operates with the parameter N313. In addition, the timer Τ3〇2, the parameter N302 and the counter (or variable) V3〇2 are used for the cell update or wireless communication access area registration (UTRANRegistration Area, URA) update procedure. The counter V302 is set by the user terminal. It is not received through the system information block. Similar to the aforementioned problems to be solved, how many timers and parameters are used in the Long Term Evolution system to detect or handle wireless link failures, and how to set this 200818787 Timing (4) is still pending. In addition, it may have multiple standards of Mobility and service quality. For example, for the client, the services from the providers of the same-game or multimedia broadcast and multicast services can be instant or non-instant, and their action criteria can be divided into "none", "low", " Medium or high. As a result, a service application sometimes needs to start a cell update program or an I1 Random Access Procedure. On the other hand, for some applications, the timing of a fine wireless link failure is critical. Long-Term Evolution • The system's random access procedure is used to handle wireless link failures, which have similar functions to cellular update procedures, but with different techniques and procedures. In addition, the standard of action is determined by the speed and change of the client's movement, as well as the scope of the service. For example, the service range of a home base station is less than that of a wide area base station. Therefore, in the Long Term Evolution system, the timers and parameters at both ends of the UE and the enhanced base station (εν〇_NodeB 'eNB) can be updated and reset without relying on radio bearer reconstruction (B_"Re_eStablishment). Expected, for this, 1 by the initial cell update program or the same function of the program (such as random storage) Xiao Yu recovery hotline link failure timer and parameter set value assumption is in the system _ evolution bearer service Established to receive the lie.

The cell update program of the evolved system in this document is used to describe the procedure for establishing or updating the location of the client terminal. 200818787 [Invention] Accordingly, the present invention provides a packet exchange service field for a wireless communication system. The method for processing a wireless link failure and its related device. 7. The present invention discloses that a packet exchange service domain in a wireless communication system is processed - a wireless link failure financial method. The financial method includes use,
